Garden of life is the number one brand! Jordan Ruben is a trusted name! My wife's doctor recommended a probiotic. Once we started researching we decided it would be beneficial for our entire family to be on a probiotic. MAN WHAT A DIFFERENCE! We even ordered the chewables in this same brand for our kids. No more tummy ache complaints. A little history... last year our entire household suffered from walking Pneumonia. We were all on some pretty strong antibiotics.We wish someone would have told us then to follow up any antibiotics with a probiotic to restore the good bacteria in our gut. Unfortunately the walking Pneumonia led to a more life changing diagnosis for my wife who was then diagnosed with myalgic encephalomyelitis. This probiotic is an essential part of her supplement routine everyday. The great thing about this specific brand is the number of live cultures. With supplements we have learned you get what you pay for. Yes, this may be a little pricey... but what price can you put on good health? Pair this supplement with the "Eat Dirt" book by Josh Axe. Its life changing! Heartburn, gut and digestive issues, so many issues in our body start with the gut. This probiotic is a good start to healing
